In parts of Europe, a log was burned at night from Christmas to Twelfth Night.Next year's log was lit with what was left of last year's log.The French keep the tradition alive in cake form!
Whip cream and mascarpone together, fold in cranberry sauce and chopped raspberries, spread onto cooled cake and roll up. Cut a piece off and attach with some filling.
Make ganache and chill until spreadable.
Spread onto the outside of the cake. Leave ends unfrosted so you can see the roll and filling.
Make "bark" using the tines of a fork.
Decorate as desired.
